ecent years have witnessed the commissioning of coherent x-ray sources opening the new field of x-ray quantum optics. While
not yet as advanced as its optical counterpart, it may enable coherent control of x-rays, with potential applications for the fields
of metrology, material science, quantum information, biology and chemistry. Compared to optical photons, x-rays profit from better
detection, robustness, high penetrability and, due to their shorter wavelength, focussability, pushing the diffraction limit far beyond
present-day limitations. These advantages bring into focus x-rays for promising applications for instance as future information
carriers, or for novel probing technologies based on quantum effects. Due to their suitable transition energies, nuclei rise as candidates
for the resonant interaction with coherent x-ray light. Here, we investigate how to use nuclear transitions in the x-ray regime to
manipulate single x-ray quanta. The key for such control is the use of Mossbauer transitions in solid-state targets which enable
collective effects to come into play in the nuclear excitation and decay processes. Particularly successful systems to exploit collective
effects of nuclei in x-ray single-photon superradiance have proved to be thin-film planar x-ray cavities with an embedded

layer. For instance, we have shown that narrow-band x-ray pulses can be mapped and stored as nuclear coherence in a thin-film
planar x-ray cavity with an embedded iron layer. Further control can be achieved by coupling x-ray quanta to an optomechanical
device. We have demonstrated theoretically that using resonant interactions of x-rays with nuclear transitions, in conjunction with
an optomechanical setup interacting with optical photons, an optical-x-ray interface can be achieved. Such a device would allow to
tune x-ray absorption spectra and eventually to shape x-ray wavepackets for single photons by optomechanical control. We show that
optomechanically induced transparency of x-rays can be achieved in the optical-x-ray interface paving the way for both metrology
and an unprecedentedly precise control of x-rays using optical photons.

Biography
Adriana Palffy has studied Physics in Bucharest, Romania, and received her PhD in theoretical physics at the Justus Liebig University in Giessen, Germany.
Since 2011 she is the Leading Scientist of the group Nuclear and Atomic Quantum Dynamics at the Max Planck Institute for Nuclear Physics in Heidelberg,
Germany. Among her research interest, covering the interface between atomic and nuclear physics and quantum optics, she has been an active participant in the
development of the burgeoning field of x-ray quantum optics. Seminal works include the theoretical study of the interaction of x-ray free electron laser radiation with
matter, storage and coherent control of single x-ray quanta, and an optomechanical interface of optical and x-ray photons.
